CARTRlDGE-CRAMP FOR MAGAZINE-GUNS.

SPECIFICATION forming part of Letters Patent No. 449,287, dated March 31, 1891.

Application filed April 26, 1890. Serial No. 349,632- (No model.)

T all whom, it nccty concern.-

Be it known that I, KARL KRNKA, residing at London, England, have invented an Improved Oartridge-Oramp for Magazine Repeating Fire-Arms, of which the following is a specification.

My invention relates to a fitting adapted for use to a magazine repeating rifle or firearm, whereby a number of cartridges may be held together in packets and be applied in such packets to the open mouth of the slot through the stock of the gun communicating with the magazine, and my improvements therein specifically relate to the following I 5 items: The said fitting or cartridge-cramp is so constructed with an arched back that the cartridges are disposed slightly radially to one another, the rim of each cartridge resting directly upon the rim of the next cartridge below and not stepped one behind the other. The cramp is provided with elastic wings of such a depth as to steady and secure the cartridges in position in the cramp. The cramp is similarly constructed at either end, so that 2 5 it may be applied to the stock of the gun for feeding with either end downward. The side wings are made to terminate with inwardlybent ends, serving to retain the outside cartridge at either end within the cramp,and also 0 serving to automatically discharge the cartridge-cramp from the stock by the reaction of the said wings upon the rounded surface of the last-delivered cartridge, causing the cramp to automatically spring out of its at- 3 5 tachment to the upper spring-wings of the magazine.

In order that my invention maybe the bet ter understood, I now proceed to describe the same in relation to the drawings hereunto anneXed.

Like letters refer to like parts throughout the various figures.

Figure 1 is a general elevation of my cramp filled with cartridges and applied to the car- 5 (ridge-chamber of a magazine-gun. Fig. 2 is a front elevation, looking between the checks of the said cra1np,with the cartridges removed. Fig. 3 is a longitudinal section through the said cramp, showing the indented tongues Z pressed inward. Fig. 4 is a side elevation of the said cramp with the cartridges removed.

On either end of the cartridge-cramp one of the sides overlaps the other by its double width. Near the rear wall the sides Zare perforated and slit at each end i to increase their elasticity.

To prevent the cartridges from falling out of the cartridge-cramp, both ends of the wings Z are somewhat bent inward at Z at a rightangle at each end.

To allow of the cartridges being pressed easily downward from the cartridge-cramp, the cartridge-rims are not in a straight-line groove but in an arched groove, so that the cartridge-rims are not placed beside each other,

but above each other, while at the same time the front parts of the cases of all five cartridges touch one another. The back of the cramp is indented with tongues Z on both ends, rising slightly into the bend of the groove (see Fig. 3) to prevent the accidental slipping of the cartridges. The cartridgecramp can therefore be emptied from either side, and the sides Z, in consequence of their depth and position, effectively prevent the shaking of the cartridges and have the other following advantages.

As shown in Fig. 1, the filled cartridgecramp is placed in the corresponding recess of the shoe. Whether this is done with one end or the other the narrow end of one of the two sides Z is always situated upward to the right of the rifle. The cartridges are then pressed downward with the thumb of the right hand one by one, the cartridge-cramp remaining stationary, as the lower end Z Z of the two sides Z-Z rest against the elastic magazine-lugs k Directly one-half of the last cartridge had left the cramp the latter is thrown upward out the stock or shoe on account of the elasticity of the two sides Z Z and the rectangular bend of the edges Z Z of the sides slipping snddenly off the surface of the cartridge. In this manner my improved cartridge-cramp is extracted automatically from the gun-stock when empty without any special device on the rifle and saves the rilleman the trouble of extracting it by hand.

Having fully described my invention, what I desire to claim, and secure by Letters Patent, is-

A cartridge cramp in which a trough- 5 shaped back is extended in a lateral wing on either side, embracing the sides of the cartridge, the said wings being wide at one end and narrow at the other, alternated at either side, so that the cramp may be used equivaro lently either side upward, the upper and lower edges Z Z of the said wings being turned inward at right angles to automatically throw the cramp out of the receiver when the last cartridge has been pressed into the magazine, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

KARL KRNKA.
